Q:motorcycle valves compression?
Yes it can lose compression if your valve lash is too tight. This can also cause the valves to burn. Adjust your valves as soon as you can.
Q:wheres the egr valve?
You egr valve will be located on the exhaust or have a metal tube running from the exhaust the other side of it will be mounted on or near the intake. you can also look at the vacuum routing label on the hood if it is vaccum controlled it will be listed on the diagram
Q:Can I take a reversing valve from a heat pump.?
problematic thing. research from search engines like google. just that can help!
Q:First trumpet valve always gets stuck?
You need not replace the valve, but it does need a bit of attention. There are many possible reasons for the sticking and you can spend a long time trying to chase them down. Inconsistent sticking suggests 2 likely reasons (there are several more possible reasons). The first is piston wear that has slightly misshapen the valve casing so it sticks because it doesn't travel through the valve casing exactly the same way every time. The second is that the felts and corks are worn and need to be replaced. The best thing for you to do is to take it to a shop, describe the problem and spend a few bucks to get it fixed right.
Q:What Does It Mean To Need A Valve Job On A Car?
honestly u prolly shouldnt get the car if he says it needs a valve job, cause he prolly doesnt know waht he is talking about, and if it needs a valve job that means it needs new valves so it may not be worth it valves let air in and out of your cylinder, the intake valve opens to let air in, the piston rises creating pressure, the fuel injectors add gasoline to the air, the spark plug ignites to explode the gas/air mixture, the exhaust valve opens to let the ignited gas/air mixture out. that is the basic works of that part of the motor a valve job is having the sides of a valve ground to allow for better air flow and to seat better against your head
Q:Anybody with a valve replacement?Which valves do u think are more successful,mechanical or natural?
Usually with an artificial valve, you'll need to be on a blood thinner for the rest of your life. If they use a natural valve, you usually won't need the blood thinner - perhaps you will for a little while, but not permanently. You can request a natural valve, but the surgeon doesn't know what size/shape of valve you need until he actually opens you up and sees what he's working with. He has an idea, based on the x-rays and MRIs you've had done, but he won't know for sure until he actually see it. So the surgeons are going to request that the Organ Procurement Department to thaw out two or three valves, depending on what they see in the tests. You can't just keep thawing out valaves, testing them, and then refreezing them if they aren't what you are looking for, so if they turn out to not be a good fit, he's going to turn to an artificial valve. So you could request a natural valve, but because of the shape of the gap that he needs to fill, you may have to have an artificial valve. Blood thinners scare people, and your friends will tell you horror stories about how their uncle's cousin's Nephew cut his arm and bled to death because he was on a blood thinner! That could happen, but it is very rare. What does happen is that you will have to go to your doctor once a month and have a blood test, and if your blood is too thin, you need to ease off on the blood thinning medication. Or if it is too thick, you need to take more. If you're blood is too thin, you'll bruise more easily - which might be embarrassing if the bruise can be seen. Blood thinners aren't as dangerous as they make them out to be, but they can be inconvenient!
Q:Is valve oil and rotary oil the same?
Yes and no. Most pro repair shops use a heavier oil on the bearings and your valve oil on the inside of the valve. Confused? On both ends of the valve are the real friction points, the bearings. One can be seen under the valve cap. Take the cap off and push the valve, the little post you see moving in the middle is the bearing. The other one is on the underside. It comes out of the valve body and has the string post screwed on it. The only point to oil the bottom bearing is that little crack you see where it comes out of the valve body. You put a drop of sewing machine oil on those 2 bearing spots, 3 in 1 oil also works. Then pull a valve slide and put a few drops of valve oil down into the valve. That is how it is done. BTW, there is no difference between valve oil and rotor oil most of the time.

Q:Cheaking the Valves?
Bad valves won't cause the problem you're describing. This is something you need to have a mechanic look at. It sounds to me like you may have an issue with a timing chain or timing belt that has jumped or it's possible that you've got a blown head gasket between a couple of cylinders. There are other possibilities too, most of them not very good. Unless you know what you're looking for, you won't be able to diagnose this yourself.
Q:Trumpet valves keep sticking!?
My trumpet does that a lot, so i rub it w/ a paper towel, loll blue juice valve oil is the best.
